I would follow tibbe's Haskell style guide[3] because it is strict and reasonable. To quote it on this topic:
"Always use explicit import lists or qualified imports for standard and third party libraries. This makes the code more robust against changes in these libraries. Exception: The Prelude."
[3]: http://github.com/tibbe/haskell-style-guide/blob/master/haskell-style.md
The possible advantage in robustness is pretty small - if the imported library adds and exports a new definition using a name you were already using then you'll get a name conflict. The GHC style guide has better[*] reasons for avoiding them: http://hackage.haskell.org/trac/ghc/wiki/Commentary/CodingStyle [*] "Better" - as in it conforms to my prejudice.... Best wishes Stephen
